ESP-201

I've several ESPs, some ESP-01, 1x ESP-03 (but it went to scrap when I've try to upgrade Flash, solder pads went off), 5X ESP-07, 3x ESP-12, 3x ESP-12E and now 1x ESP-201.

I'm very very disappointed with the ESP-201 module I've received today.
It is resetting all the time, although I'm followed my own "best practices" about PullsUps. :o
It seems that on this board there some additional PullUps required, but undocumented ... :?

I had the same problem
Now i have tried to connect RST to Vcc through a 10 kohm resistor, and that seems to work

Edit:
No it did not help
I'm a bit confused about the connections
This guy says to pull GPI02 high, can that be right ?

My usual recipe is GPIO15 pulled down, GPIO2/GPIO0/RES/CH_PD pulled up.
But it still reseting while I'm approaching my hand nearby.
So, there must be another sensitive pin ..

Thankyou martinayotte

With your connection my ESP-201 seems stable, I can touch the board all over with my fingers without it resets.
